Question

An average person’s heart beats about 103,680 times a day. Write and solve an equation to find about how many times the average person’s heart beats in one minute

Answer 1

1 day = 24 hours
1 day = 103 680
therefore 24 hours = 103 680 
                    1 hour = 103 680 ÷ 24
                               = 4320

1 hour = 60 mins 
1 hour = 4320
therefore  60 mins = 4320
                   1 min = 72 beats
